Don't share nodePort service in session affinity tests
**What this PR does / why we need it**:
From https://github.com/kubernetes/kubernetes/issues/54524, https://github.com/kubernetes/kubernetes/issues/54571.
Spent sometime to dig into it today, found this test is flaky mostly because it sends out service requests before kube-proxy reacts on the service session affinity update, hence multiple endpoints are responding instead of one. It is more flaky in alpha CIs probably due to different test sequences.
This PR creates a separate service with `sessionAffinity=ClientIP` so there wouldn't be a race between test begins and kube-proxy reacts. On the other hand, it also seems inappropriate to tweak the`config.NodePortService`, which is shared by other networking tests.

Fix Incorrect Scale Subresources and HPA e2e ScaleTargetRefs
The HPA e2es failed to actually set `apiVersion` on the created HPAs, which previous was ignored. Since the polymorphic scale client was merged, this behavior is no longer tolerated (it was never correct to begin with, but it accidentally worked).
Additionally, the `apps` resources have their own version of scale. Until `apps/v1beta1` and `apps/v1beta2` go away, we need to support those versions in the scale client.
Together, these broke some of the HPA e2es.
Fixes#54574
```release-note
NONE
```
apps/v1betaX inadventertently contains its own variant of Scale. In
order to support scaling Deployments, ReplicaSets, etc, we need to support
these versions of Scale as well.

Remove federation
This PR removes the federation codebase and associated tooling from the tree.
The first commit just removes the `federation` path and should be uncontroversial. The second commit removes references and associated tooling and suggests careful review.
Requirements for merge:
- [x] Bazel jobs no longer hard-code federation as a target ([test infra #4983](https://github.com/kubernetes/test-infra/pull/4983))
- [x] `federation-e2e` jobs are not run by default for k/k
**Release note**:
```release-note
Development of Kubernetes Federation has moved to github.com/kubernetes/federation. This move out of tree also means that Federation will begin releasing separately from Kubernetes. The impact of this is Federation-specific behavior will no longer be included in kubectl, kubefed will no longer be released as part of Kubernetes, and the Federation servers will no longer be included in the hyperkube binary and image.

Fallback to internal addrs in e2e tests when no external addrs available
This change modifies the way that config.NodeIP is selected at the
start of e2e Networking tests such that if no external addresses are
available from the cloud provider (e.g. either no cloud provider being
used [baremetal or VMs], or the provider doesn't have external IPs
configured), then one of the internal addresses is used.
Without this change, the e2e service-related Networking tests will always
panic when config.ExternalAddrs[0] is accessed and the slice is empty.
This change eliminates the panic, and in some setups, the fallback choice
of using an internal address will provide the necessary connectivity
for the e2e Networking tests to access each node.

When starting an e2e test in a pod in a cluster, if the host is

'http://127.0.0.1:8080' currently. We should be discovering the
host/port using the in-cluster config and using that if
possible.
